Add an nvim Module that configures Neovim declaratively through nixvim,
wired as a flake input and consumed as its home-manager module. Options,
globals, keymaps, and plugin settings are typed Nix; the colorscheme
call and two autocmds live in modules/nvim/config.lua via extraConfigLua.
Plugins come from nixpkgs (no plugin manager, no runtime cloning); git,
ripgrep, and fd are provided from Nix; treesitter grammars are built by
Nix so no runtime compiler is needed.
Functionally matches the previous config (plugins, keymaps, options, the
nord colorscheme, markdown conceal, the Neogit blame toggle), verified
headless against the generated init.
Add disko as a flake input (following nixpkgs) and wire its NixOS module
into the host-builder, so any Host can declare a disk layout while the
layout itself stays a per-Host concern.
neogaia's layout (hosts/neogaia/disk.nix): one GPT NVMe disk with a
systemd-boot EFI system partition and a LUKS container holding btrfs with
@root/@home/@nix subvolumes. The initrd prompts for the passphrase on a
normal boot. Swap is RAM-backed zram, so there is no on-disk swap
partition; zramSwap is enabled directly for now (task 0003 lifts it into
a toggle Module). The task-0001 placeholder fileSystems are removed since
disko now derives them.
26.05 is the latest stable NixOS release as of now (26.11 is still the
in-development branch that nixos-unstable reports); the previous 25.05 pin
was a release behind.
- flake.nix / flake.lock: stable overlay tracks nixos-26.05.
- neogaia system.stateVersion and the base home.stateVersion set to 26.05
(fresh install, so aligning to the current stable release).
- Refresh the "latest stable release" references in CONTEXT.md, the spec,
and the task file to match.
Other inputs are rolling branches (nixos-unstable, nixpkgs-unstable,
chaotic nyxpkgs-unstable) or master (home-manager, per spec), so they carry
no version to bump.
Stand up the walking skeleton the rest of the laptop MVI extends and
re-verifies against: the whole neogaia Host evaluates and its system
toplevel builds (nix flake check green).
- flake.nix: hand-rolled flake (no flake-parts). Base nixos-unstable, plus
nixpkgs-unstable and nixos-25.05 for the per-package unstable/stable
overlays, home-manager (nixpkgs followed), and chaotic-nyx (deliberately
not following our nixpkgs, to keep its binary cache usable). checks build
each Host toplevel.
- lib/: trimmed helper lib — the Auto-loader (recursive .nix discovery, no
null-placeholder hack), the host-builder, and the script-from-file helper.
Deps inherited explicitly; no with lib.my, no nixosModules output.
- system/: shared base config — the unstable/stable overlays, the user
option (defaults to alexion, in wheel, drives system + home-manager user
in lockstep), flakes, git, and home-manager as a NixOS module.
- modules/example.nix: Auto-loader / Enable-convention reference Module,
inert until enabled.
- hosts/neogaia/: minimal laptop Host — placeholder filesystems, bootloader,
and hardware profile, all superseded by disko in task 0002.
- CLAUDE.md: project agent instructions with a Gotchas section (nix on the
CachyOS dev host, the chaotic overlay/cache behaviour, tea/Gitea).
